| Popis: |
The new Structurally Integrated BiologY for Life Sciences (SIBYLS) beamline at the Advanced Light Source will be dedicated to Macromolecular Crystallography (PX) and Small Angle X-ray Scattering (SAXS). SAXS will provide structural information of macromolecules in solutions and will complement high resolution PX studies on the same systems but in a crystalline state. The x-ray source is one of the 5 Tesla superbend dipoles recently installed at the ALS that allows for a hard x-ray program to be developed on the relatively low energy Advanced Light Source (ALS) ring (1.9 GeV). The beamline is equipped with fast interchangeable monochromator elements, consisting of either a pair of single Si(111) crystals for crystallography, or a pair of multilayers for the SAXS mode data collection (E/ΔE~;1/110). Flux rates with Si(111) crystals for PX are measured as 2x1011 hv/sec/400 mA through a 100μm pinhole at 12.4 KeV. For SAXS the flux is up to 3x1013 photons/sec/400 mA at 10 KeV with all apertures open when using the multilayer monochromator elements. The performance characteristics of this unique beamline will be described. |
